The acceleration vibration really is "normal" I think.

No, it isn't. My '06 Silverado does not have it, my '09 Impala does not have it, my brother's 2013 Infiniti G37 6MT does not have it, and my 2013 Chevy Sonic does not have it. The first two vehicles listed have automatic transmissions, the other two have manual transmissions.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Well guys. GM wasn't helpful. They closed the book on my vibration problem. I hope you have a great relationship with your dealer like I do. Now it is me and the dealer. Stop trying the stupid tires, rims, drive shaft, bull shit. My dealer has some ideas I am hip to that they are trying. I am assured that I will be ok in the end. God help you.

If you are talking to GM customer service you might as well talk to the cat's ass hole. Not going to get you anywhere. Call Pat at 866.790.5600 Ext 11586. Her breath smells like cat shit. Will keep you posted.

Last weekend I was trying to figure out how much the High Country vibrated and rode rough compared to the new wife's Z71. I looked for devices that would measure the vibration, they were all expensive.

Then it I had an idea, one of my hobbies is photography and a camera mounted rigidly on a vehicle will magnify the vibration.

I am not sure we can post links on this forum, but above is the video.

Let me qualify it a bit. Mounted like this the camera would magnify vibration. The trucks do not vibrate this much but it I did it to give myself a comparison. Both cameras were mounted on the head rest mounts identically in both trucks.

The new Z71 4x4 is on the left, it has a 3.5" Rough Country lift and 305/55/20 Nitto Terra Grapplers. It has 1200 miles on the truck.

The right is the High Country with 285/55/20 Nitto Terra Grappelers. It has 5500 miles now.

 

Edit: I should point out that the trucks were driven on the same road about 30 minutes apart, the Z71 on the left is slightly ahead of the High Country. The Cruise on both is set at 40mph.

 

I took the truck in earlier this week. According to the dealers service department the ride is due to the rigid frame of the High Country. I am waiting to hear back through the Dealer from GM for an explanation as to why Chevy's top end truck rides so rough.

Mroma are you still on this forum? Did you swap from a chevy to gm, and also why did you pick the z71, was something said to you from GM that led you to swap into this model? I want out of mine, but not sure I want to get into another one that might also vibrate!

You may want to check your driveshaft for any radial runout or wobble as shown in this clip:

A chattering torque converter can certainly cause transmission vibration that is then transmitted through floorboards and seats.

Did you show them this video? That should be some good proof for them.

I gave it to the dealer with a nice letter about the vibration and ride. The dealers service guys still said the ride was because of the High Country's rigid frame versus the Z71's.

 

I also copied Chevy's news release they put out at the release of the High Country and underlined a few things. These are excerpts from Chevy's High Country news release;

 

"A fully boxed frame with the main rails and major cross members formed from high-strength steel provides a rigid base for maximum hauling capability, as well as greater noise and vibration isolation – contributing to the Silverado High Country’s balance of segment-best capability and industry-leading refinement.

 

The stiff chassis enables more precise tuning of the front and rear suspensions, giving the Silverado a more responsive feel with smoother performance and less vibration and shake, particularly on harsh terrain."

 

The ride I am getting from the High Country doesn't match Chevy's sales hype. I am waiting to see what GM says.

* It has lower noise and vibration levels than a WWII T-34 Russian tank.

Why are they advertising fully boxed rigid frames as the best solution? They obviously have some serious drawbacks too.

Mine is now a couple of years older.... but I have to say... ALWAYS have had a vibration! I have had it to the dealer several times. Balance, re-balance the wheels, had a tire replace that was "believed to be the culprit" but nothing fixed!

 

My truck has done this since day one, with the original 20" chrome cladded wheels from factory (as ordered). I have to say, sadly getting used to it... My friends have trucks, I've been in them, I take note of smoothness and a quite ride. I have always had that 60 mph at times, but mostly over 65mph vibration that continues/increases with speed. Worse on a black top or asphalt expressway/highway... seems a bit smoother on the concrete type roadways for some reason. It just seems to not be as apparent.. even seems absent on these roads in many cases.

 

Bugs Me! Bugs Me! BUGS ME!!!! I am thinking, hoping that once I put some new tires on it, it may hopefully go away. I have thought that perhaps its the 20" wheel which is basically an aluminum wheel with a plastic wheel cover that is glued on. Maybe excessive glue I thought, as in globbed on too heavy on one side of the wheel... ? Maybe these wheels are prone to vibration due to a design flaw, uneven in weight distribution... I don't know!

 

I am also considering going with different wheels, eliminating the cladding wheel type. I would like to go with an all terrain type tire but am afraid that those may worse the problem. I may go with an all season high quality Michellin in hopes of resolving... if not, for the $$$, I will be more upset.

 

In an regard... there are issues! They should be resolved once and for all. At the dealer, they make you feel like the issue is just with your vehicle. I feel that there are many more of us out there... many just don't openly complain. But it's justifiable...

Mundfund,

 

I have the same exact issue as you're describing. Unfortunately I have this issue too and after 5 sets of tires and 2 sets of wheels, cladded and non cladded, they don't seem to have any impact on the vibration and as you said it's present at 65-up.

They are just blowing you off.. They ALL HAVE THE SAME FRAME.. only the suspension is different.. softer springs/shocks on the High Country which would (should) give it a smother ride...

Time to zero in on the driveshaft and the torque converter.

      Towing In Loose Gravel

      By diyer2 · Posted

      I had a boat for many years, never had a problem even with a 2 wheel drive 93 Silvy for 20 years. Good tires, proper use of the gas pedal worked.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I read through that and I won't lie, my eyes rolled at some of the quirks about how it can turn off the trailer braking for example but I can see how it could help control or even up the torque applied to the ground with each wheel in a boat ramp scenario. But of course what it can't do is increase the torque to the wheels if the need is there as it ends up being like driving the four wheel drive version of a two wheel drive ( high range that is ). So far the neighbor that ended up with the 3.0 duramax with the max tow package which meant the 3.73 gears and high range only, I think its been doing ok for what he has been towing but doubt he ventures off into the soft stuff with his holiday trailer. He may have towed his dads river boat locally with it ( he always used his 6.6 duramax before ), I'll have to ask him sometime if he got into a lack of power to the wheels situation as after all that engine produces a lot of torque at low speed once the turbo winds out a bit and I think it has the 10 speed and if so they have a pretty good first gear ratio at 4.70 I see which is vastly better than the 3 or four speed overdrive models of years ago.

      OCI, not when but why?

      By diyer2 · Posted

      I did shorter OCI"s for many years without an issue, fights sludge and wear IMO. Recently started using Amsoil, will not do the recommended/advertised miles between changes.

      OCI, not when but why?

      By Chuck FB · Posted

      It definitely seems quite evident that emissions and fuel economy targets rule above the best case scenario of what the engines best health and life could be otherwise. Items like DI and turbo DI engines with their LSPI issues as well as cats being reduced in life if the proper levels of certain additives were allowed to be utilized and so something has to be compromised and as you point out that is the engine protection from sludge, acid and wear which isn't in the manufactures best interest regardless to worry about in this race to profits from higher sales and so if the engines wear out sooner the next sale is closer at hand.    I am hearing that its likely the two new 2027 GM half ton truck engines will call for a 0W-30 oil, now if that is an existing oil I would have to think so but we will see in the coming months. Sadly as you've pointed out to me, over the last number of years the push has been on to reduce the actual operating temperature viscosity within each designated viscosity grade so that 11.5 to 12 range for a 30 weight for example is more in that just above 10 range at 100c along with that temporary viscosity sheer dropping it even further down as per that "energy conserving" designation, not to mention how some oils are not as sheer stable as would be ideal and that mixed with a long OCI paints a picture with a little too much glitter shall we say !.    All that and the warranty gods scaring the vehicle owner into sticking with that watery wine or risk loosing their warranty coverage if they go and use an oil that is of a higher viscosity even if it meets the emissions and LSPI requirements and would never damage the engine but may very well allow for an engines longer life depending on engine use scenarios ... high ambient temps, towing etc that push oils to their limits.
